When checking the "Perform all 32-bit float operations as 64-bit" checkbox in Visual Studio (on the "Advanced" tab of the "iOS Build" section of the project properties dialog), the value of the <MtouchFloat32> property is set to "True".
When checking the equivalent checkbox in Visual Studio for Mac, the value of the <MtouchFloat32> property is set to "false".
When unchecking, the opposite happens: VS => MtouchFloat32=false / VSMac => MtouchFloat32=true
*Unchecking* this option should set the property to *true* / *Checking* should set to *false*:
Visual Studio for Mac does the right thing. Visual Studio for Windows does not.

Non-engineering team preliminary quick review
(See https://developer.xamarin.com/guides/cross-platform/troubleshooting/questions/howto-file-bug/ for general reference.)
## Suspected to be a regression or a problem with a new feature?
Uncertain. I was not able to reproduce the issue with VSforMac [Version Preview 5 (7.0 build 1659)] or Xamarin Studio [v 6.2 (build 1829)]
## Specific to one particular project, development computer, or target mobile device?
Uncertain. This is issue reported for VS Mac
## Includes clear steps to reproduce the problem?
Yes. But, I was not able to reproduce the issue with the steps provided.
## Considers the relevant log files for the part(s) of the process where something goes wrong (IDE editing, MSBuild building, deploying, launching, attaching the debugger, an in-app error, or something else), and has them attached?
Does include Version information from the VS for Mac
## Already took up time for many users?
Unclear. This is the only report I have seen for this issue.
## Makes development (a) difficult, impossible, or potentially hazardous, (b) moderately inconvenient, or (c) mildly inconvenient for users?
I would say (b) based on the description, but since I can not reproduce the issue it is hard to say if this is an issue with the specific project the bug reporter is using or an issue in the Xamarin tools. However it might be (b) or (c) if the issue can be avoided by editing csproj file
The bug is in *Visual Studio (for Windows)*. VS for Mac and XS do the right thing.
This is not yet fixed in XVS 188.8.131.521, but will be fixed in the next release.
Fixed in version 184.108.40.2062 (master)

Hi @Frank Buckley, it will be great if you can provide steps for verification?
1. Open Visual Studio and create a new Blank iPad App.
2. Open project properties and navigate to iOS Build section – Advanced tab.
3. Check "Perform all 32-bit float operations as 64-bit".
4. Save the project.
5. Open the csproj file in a text editor.
6. Confirm that for the appropriate configuration (e.g. Debug|iPhoneSimulator) the property MtouchFloat32 is set to false – i.e. <MtouchFloat32>False</MtouchFloat32>
7. Open project properties and navigate to iOS Build section – Advanced tab.
8. _Un_check "Perform all 32-bit float operations as 64-bit.
9. Save the project.
10. Open the csproj file in a text editor.
11. Confirm that for the appropriate configuration (e.g. Debug|iPhoneSimulator) the property MtouchFloat32 is set to true
